Kim Bergman, these are the specifications I am looking for.

-LCD display with 3-4 lines with 16 or more characters displayed per line.
- LCD temperature range (55-70) degrees.
-The keypad should have at least 14 keys
-10 number keys
-Up and down keys
-1 enter key and 1 cancel key.
-built in driver and serial port (can you provide software, tutorials and firmware drivers with the driver to reduce programming time?)
-Unit could have a built-in microcontroller but it
is not necessary.

If you have something that is very close to what I have described please let me know ASAP. I will be very interested in looking at it.
Thank very much!
